The first of the three reactions in this series is:
28Si + 28Si => 56Ni + gamma + 10.9 MeV
Whether or not that gamma is thermalized efficiently, e.g., via internal
conversion, the heat will be released into the environment, in contrast to
the energy that is lost in the subsequent reactions from neutrino
emission. If we assume 1.3 tons excess iron following Narayanaswamy, then
the amount of energy released into the environment for this first reaction
would be:
1300 kg 56Fe = 23241.288159 mols 56Fe
23241.288159 mols (28Si + 28Si) = 46482.576318 mols 28Si = 1300.4396227
kg 28Si
1300.4396227 kg - 1300 kg = 0.4396227 kg => 3.9e16 J
That is to say, (3.9e16 J / 84 TJ = 464 "Fat Man" nuclear bombs per 24
hours).
